I needed the latest version of a particular package and using “] add Package” didn’t do the trick.

I knew the change I wanted had been pushed to master, so in the docs, I saw that you can use the notation (which is very cool):

Package#master

so I did “add Package#master”, and presto I got the change I was looking for.

However… I’m unclear what, if anything, I’ve done to the package state. Is there anything I need to do to pick up the “official release” at some point in the future ?

Thanks,

`]free Package`  
will make it follow the official release again.

Thank you!

Thank you, and a big DOH! award to myself. It turns out my exact case is described in the Pkg documentation under the section “Adding Packages”.
